Digital Signal :
Direct Modulation :
Receiver Analogue Signal :
Bias Voltage = 2.8V
Set Low to switch the receiver on. Used in conjunction with TXON:
MUX1 and MUX2 connect one of the three data inputs to the transmitter
in the following way:
Receiver Digital Signal. The ANOUT signal is processed and presented in
Carrier Detect; high when an RF signal of sufficient strength is present
Out of Lock Signal. Output set low if synthesiser has not locked within
RF S
Analogue Signal : Maximum deviation at 1Vpk-pk, bandwidth 6Hz to
2000 REG No 277 4001, ENGLAND.
High to low transition increments or decrements the RF channel.
0V=No signal, 0.7V = 0. mV, 1.6V = 10 mV, 2.4V = 100 mV
Serial status Data Out. Used in conjunction with SRX
YNTHESISED
Voltage logarithmically proportional to signal strength
Serial status data; TTL Level 9600baud no parity
Serial set-up data; TTL Level 9600baud no parity
Low when serial status data is present on STX
Power Supply +ve, regulated 8.5 - 14V supply.
Power Supply +ve, regulated 8.5 - 14V supply.
70mSec of TXON or RXON being applied.
LOW sets FCNT to decrement channel
HIGH sets FCNT to increment channel
Set low when synthesiser has locked
Set low to switch on the transmitter
Set high when in transmit or receive
Floating input = Max RF Power
4KHz, 3K
